13-year-old Marcelo and his younger brother leave their Venezuelan home at 4.30 am every day, to walk unaccompanied, in the dark, for 2 ½ hours, to attend school in Colombia. Their lessons start at 6.30. They slip into Colombia through informal border crossings known as trochas - dangerous rural dirt tracks weaving across the arid border, controlled by local armed groups, drug gangs and smugglers who often charge users a fee to pass through. In a sign of teenage bravado, Marcelo denies being scared of journeying through these crossings: he says, ‘I like coming to school in Colombia. They don't ‘have lessons where I live’. Venezuela's crumbling economy and socio-political crisis have pushed institutions to the brink. Rural schools are neglected, offering only a few lessons a week with a critical shortage of teachers. Official border crossings have reopened, but sadly few have the necessary papers to use them.
